Ingredients

Instructions

  • Preheat the oven to 375 degrees F, and line baking sheets with parchment paper.
  • Place the butter, brown sugar, and granulated sugar in a large mixing bowl, and cream together on medium-high speed for a FULL 5 minutes, scraping the bottom and sides of the bowl with a silicone spatula as needed.
  • Scrape the bottom and sides of the bowl with a silicone spatula, then stir in the peanut butter, egg, and egg yolk until incorporated.
  • Add the flour, oats, cornstarch, baking soda, and salt, and mix together on low speed until just barely combined.
  • Scoop 1.5-tablespoons balls of dough onto the prepared baking sheet, pressing flat and allowing about 2 to 3 inches in between (for spreading).
  • Bake for 7 to 9 minutes, or until just barely beginning to turn golden around the edges (the cookies will still look quite wet towards the centers).
  • Allow to cool fully on the baking sheet.
